HOTJVATER BOTTLE.

Application filed December 15, 1926.

The present invention relates to hotwater bottles, and has for an object to lncorporate in the structure of a hot water bottle the features of a fountain syringe and a cushion syringe.

Another object of the present invention is to provide a flexible hot water bag of rubber or the like which is suitably reinforced to resist wearing and bursting strains at those portions which are subjected to the greatest pressure, and a bag which is so constructed that the entire length and width of the same may be utilized to the utmost.

Another object of the invention is to con struct a hot water bottle of a flexible character which is substantially bean-shaped so that it may be used as a cushion syringe and will provide a cushion of seat form with the ends thereof curved in. a forward direction to underlie the limbs and be thus compressed by the weight of the body so as to completely collapse the entire syringe throughout its longitudinal and cross sectional area.

Another object of the invention is to provide a bean-shape flexible hot water bottle with reinforcements at its ends and along its edges for maintaining the bottle in shape and to resist the various pressures and strains imposed upon the different portions of the bottle, the configuration and reinforcements being such as to prevent the bottle from creasing or kinking when pressure is unevenly applied to different portions thereof.

With the foregoing and other objects in View, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the severalviews,

Figure 1 is a top plan view of a hot water bottle constructed according to the present invention.

Figure 2 is a longitudinal section taken through the same substantially on the line 2-2 of Figure 1.

Figure 3 is a transverse section taken through the hot water bottle on the line 33 of Figure 1.

Figure 4 is a fragmentary enlarged section of one end of the bottle, as shown in Figure 2, and

Figure 5 is an enlarged section taken Serial No. 154,974.

through the front edge portion of the bottle as shown in Figure 3.

Referring to the drawing the body part of the bottle comprises a bottom wall 10 and a top wall 11. These walls are made from. flexible material, such as rubber or various compositions of the same to impartthe desired strength and flexibility to the walls 10 and 11, and so that the same may withstand the various temperatures to which the same are subjected. The bottom and top walls 10 and 11 are shaped or cut to the configuration of a bean, so to give the general bean shape configuration to the completed article. The edge portions of the walls 10 and 11 are brought together, as shown particularly in Figures 4 and 5 to provide an outstanding flange 12, which completely encircles the marginal portion of the bag. The flange 12 is given appreciable width and the contacting edge portions of the walls 10 and 11 are vulcanized, cemented or otherwise suitably secured and sealed together. The edge portion of the bag is also reinforced by an inner spreading strip 18, which may be of fabric or any suitable material which imparts stiffness to the edge portion of the bag for holding it to shape: This strip 13 is of sufficient width to overlap the seam or joint between the walls 10 and 11 and extends entirely around the inner side of the bag.

For further reinforcing and stiffening the edge portion of the bag the flange 12 is provided with an overlapping covering strip 14 which may be of flexible material and which is secured to the opposite sides of the flange 12 and which is of suflicient width to extend upwardly a slight distance as shown at 15 upon the walls 10 and 11. At the opposite ends of the bag, outer reinforcing layers or shields 16 are provided and which may be given any fanciful configuration, the shields 16 being in the form of sheets of flexible material which are secured against the outer sides of the walls 10 and 11 and which have their outer edges secured upon the opposite sides of the flange 12 and within the binding and covering strip 14.

In this instance, while the binding strip 14 iscarried on the flange 12, the edge portions of the shields 16 are interposed between the binding strip 14 and the contacting edge portions of the walls 10 and 11.

The body portion of the hot water bottle is provided at one end with the usual filler neck 17 and the hanger strap 18. Hot water or the like may thus be readily introduced into the interior of the body of the bottle, and the opposite end of the body is provided with the usual suspension tab 19, by means of which the bottle may be suspended from a hook, or the like with the filler neck 17 at the bottom in which position the bag may be used as a fountain syringe in the ordinary manner.

An important feature of this invention is the peculiar bean-shape configuration of the bag combined with the provision of a nozzle supporting nipple 20 which is mounted upon the top wall 11 of the body portion intermediate the ends thereof, and between the front and rear edges of the bag, but preferably slightly toward the front edge thereof. The rear edge of the bag is of convexformation to provide the back of a seat while the forward edge of the bag is of concave formation to form the front of the seat and to provide at opposite sides of the seat forwardly projecting portions 21 which are adapted to support the limbs and adapted to be compressed by the weight of the body, so as to effect the complete collapse of the bot tle at opposite ends and at all other parts thereof. Also due to the shape described the nozzle may be easily reached.

It will be particularly noted from reference to the drawing that the centers of the arcs described by the convex and concave side edges of the bag are located in a common plane intersecting the outlet nipple 20 at right angles to the longitudinal center line of the bag, and also that the end edges of the bag connecting said opposite side edges thereof are of substantially symmetrical curvature, the portions 21 of the bag at the opposite ends of the forward concave edge 23 thereof being correspondingly positioned at opposite sides of said plane with respect to the outlet nipple. Thus in the use of the bag, it is evident that under pressure the collapse of the spaced end portions of the bag may be easily equalized so as to concentrate the ejecting pressure upon the water contained therein at the outlet nipple 20, and relieve the marginal seam connecting the side walls of the bag of excessive lateral pressure by the bag contents. In other words, the bean-shape configuration of the hot water bottle provides a structure which supports throughout its entire length and width, and which may thus be completely collapsed at all parts.

The nipple is n'ovided with a removable eap 22 which may be substituted by a nozzle of any suitable character. The cap 22 normally maintains the hot water bottle sealed at its top, so that the provision of the nipple 20 does not interfere with the ordinary use of the hot water bottle.

The forward edge 23 of the hot water bottle is given a concave form not only for the purpose of imparting a seat iormalion to the bottle, but also for the purpose o l adapting the bottle without distortion to the limbs, the knees and the like where it is desired that the bottle contact with the limbs over a. considerable surface area. The bag thus constructed may have its opposite ends relatively flat ax compared with the bags at present used and at the same time accommodate the same quantity of liquid and also is capable of discharging under piessure the entire contents within the l ag.

I have i lust'nted and described a preferred and sail iacrory embodiment of my invention, but it is obvious that changes may be made therein within the spirit and scope thereof as defined in the appended claims.

that is claimed is l. A hot water bag comprising a body por tion having bottom and top flexible walls with their marginal edge portions secured together to provide an outstanding flange at the marginal edge of the bag, a spreading strip secured within the body portion across the joint between the bottom and top walls, an exterior covering strip secured over said flange to reinforce and stillen the same. and flexible shields secured over said bottom and top *alls at opposite ends of the bag and secured beneath said covering strip to reinforce the opposite ends of the bag against internal strain.

2. A hot water bag comprising a body portion having flexible bottom and top walls secured together along their peripheries to provide an outwardly-projecting flange, one or more flexible shields on the exterior of the bag, and a covering strip for the flange, each of said shields having one edge overlapped by said covering strip.
